Djerassi, 91, who is considered a father of the Pill, helped create the oral contraceptive in 1951. He adds parents-to-be will freeze their eggs and sperm before being sterilized, and the Pill will become redundant. He also adds more families will choose IVF methods, even if they don't have fertility issues.

"The vast majority of women who will choose IVF in the future will be fertile women who have frozen their eggs and delayed pregnancy,” he told the Telegraph. “Women in their twenties will first choose this approach as insurance, providing them with freedom in the light of professional decisions or the absence of the right partner or the inexorably ticking of the biological clock."

Djerassi claims IVF use will result in a "mañana generation," because people will have a chance to plan their pregnancies in advance. On the other hand, he says this will also lower abortion rates, since children will not be unplanned.

In addition to how women's contraceptives will change, he also says the male contraceptive pill is still unlikely.
